DETAILED DESCRIPTION

[0021] The embodiments of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0022] In the description of the utility model, it is necessary to explain, the term "center", "upper", "lower", "left", "right", "vertical", "horizontal", "internal", "external" and so on indicate the orientation or positional relationship is based on the orientation or positional relationship shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and is not indicating or implying that the device or element indicated must have a particular orientation, a particular orientation structure and operation, therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0023] In the description of the utility model, it is necessary to explain, unless otherwise expressly provided and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, can also be detachable connection, or integrally connected, can be mechanical connection, can also be electrical connection, can be directly connected, can also be indirectly connected through the intermediate medium, can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0024] As Figs. 1 to 3The utility model provides an ophthalmic micro needle holding forceps with locking function, including first clamping plate 1 and second clamping plate 2 opposite first clamping plate 1, one end of first clamping plate 1 and second clamping plate 2 is equipped with the chuck 14 for holding suture needle, the side of first clamping plate 1 close to chuck and the side of second clamping plate 2 close to chuck are hinged by hinging shaft, so that by clamping or loosening first clamping plate 1 and second clamping plate 2 makes two chuck 14 approach each other or away from each other, the clamping of suture needle is completed and is put down, the end of first clamping plate 1 away from chuck 14 is fixedly connected with first elastic plate 10, the end of second clamping plate 2 away from chuck 14 is fixedly connected with second elastic plate 11, one end of first elastic plate 10 and one end of second elastic plate 11 are mutually clamped, locking groove 4 is set up on first clamping plate 1, push block 5 is slidably arranged on second clamping plate 2, the push block 5 is connected with the clamping block 6, the clamping block 6 is adapted with locking groove 4, the clamping block 6 is set up with the clamping groove 7, in the utility model, when holding suture needle, only two fingers pinch first clamping plate 1 and second clamping plate 2 make two chuck 14 approach each other and hold suture needle tightly, in the clamping process, the clamping block 6 can be clamped into locking groove 4, and first elastic plate 10 and second elastic plate 11 are deformed, after clamping, push block 5 can be pushed to make first clamping plate 1 clamping set in clamping groove 7, at this moment, first clamping plate 1 and second clamping plate 2 are locked and fixed, even if loosening, first clamping plate 1 and second clamping plate 2 also will not separate mutually, when suture needle is transferred, can avoid the improper cooperation and lead to suture needle to drop, when needing the rest operation in the suture process, also need not long time to pinch needle holder and avoid suture needle to drop, can effectively avoid the fatigue of finger, when needing to take down suture needle, only need to push push block 5 in the opposite direction, make first clamping plate 1 separate from clamping groove 7, after loosening, under the elastic force of first elastic plate 10 and second elastic plate 11, first clamping plate 1 and second clamping plate 2 separate mutually, so that two chuck 14 separate.

[0025] Further, one end of the second elastic plate 11 is provided with a clamping plate 12, and a connecting groove 13 is formed on the first elastic plate 10 for inserting the clamping plate 12. After the needle holder is assembled, the clamping plate 12 is inserted into the connecting groove 13 to prevent the first elastic plate 10 and the second elastic plate 11 from separating. The length of the connecting groove 13 is greater than the thickness of the clamping plate 12, and the clamping plate 12 can slide in the connecting groove 13 when the first elastic plate 10 and the second elastic plate 11 are deformed.

[0026] Further, the second clamping plate 2 is provided with a sliding groove 8, a connecting rod 9 is arranged between the push block 5 and the clamping block 6, the connecting rod 9 is slidingly arranged in the sliding groove 8, and can slide along the sliding groove 8 in the sliding process of the push block 5, and meanwhile, the separation between the push block 5 and the second clamping plate 2 can be avoided, a plurality of first anti-skid strips are arranged on the side wall of the push block 5 in order to avoid hand slipping when manually pushing and sliding the push block 5, and a plurality of second anti-skid strips are arranged on the side wall of the first clamping plate 1, the fingers can be in contact with the first anti-skid strips and the second anti-skid strips when clamping the articles and pushing the push block 5, and the anti-skid effect is achieved.

[0027] Further, since the head of the needle holder has various structures, such as a curved pointed head, a curved blunt head, a straight pointed head, a straight blunt head, a straight thick head and the like, when the needle holder with different heads is used, the needle holder with the corresponding head shape needs to be taken, and the needle holders cannot be used universally, therefore, in the embodiment, the clamping plate and the clamping head are detachably connected, the clamping head can be provided with various structures with different shapes, and when different heads are used, only the corresponding clamping head needs to be replaced, and specifically, the clamping head 14 comprises a clamping portion and a mounting portion, the clamping portion and the mounting portion are fixedly connected, the clamping portion is used for clamping articles, the mounting portion is provided with a clamping groove 15, the first clamping plate 1 and the second clamping plate 2 are clamped in the clamping groove 15, and when replacement is performed, only the clamping plate needs to be taken out from the clamping groove 15 and clamped into the clamping groove 15 of the new clamping head 14, and the replacement can be completed.

[0028] Further, the side wall of the first clamping plate 1 and the second clamping plate 2 is provided with a positioning groove 16, the side wall of the clamping groove 15 is provided with a positioning block 17, the positioning block 17 is clamped in the positioning groove 16, the clamping head and the clamping plate can be fixedly connected, and the phenomenon that the clamping head is separated is avoided.

[0029] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
